1.6A 32V Synchronous Rectified Step-Down Converte TD1529
General
Dcription

The TD1529 is a monolithic synchronous buck
regulator. The device integrat two 130m.
MOSFETs, and provid 1.6A of continuous load
current over a wide input voltage of 4.75V to 32V.

 Current mode control provid fast transient
rponse and cycle-by-cycle current limit.
An adjustable soft-start prevents inrush current at
turn-on, and in shutdown mode the supply current
drops to 1μA.
This device, availablein an SOP8 package,
provid a very compact solution with minimal external
components.
